HRT1 was the only Austral Firepac used by fire services in WA. It was used for major road crash and other rescues, as well as attending large structure fires.

WA Fire & Rescue transitioned to a decentralised approach, with Heavy Rescue roles being primarily performed by Pumpers equipped with additional rescue equipment. The Pumpers are known as ‘Medium Pumper – Heavy Rescue’, with Heavy Rescue signage above the lockers of the rear body.
